Preparedness Level: (PL 2) 

Northern California Area

Preparedness Level (PL 1) 

NOTE: Thunderstorms imply gusty and erratic winds.

 SYNOP:

An area of low pressure currently over Central California will move slowly east into Nevada Thursday and into Utah Friday. This low pressure will cause temperatures to be around 5 degrees below normal through Friday, with mid 50s to mid 60s across the mountains and upper 60s and 70s in the valleys.  A weak ridge of high pressure will build toward the California Coast from the southwest causing temperatures to warm a couple degrees this weekend.  Cooling will take place once again early next week as another low drops into California from the Pacific Northwest.  Instability will bring isolated afternoon showers and thunderstorms to the Sierra through early next week.  Westerly afternoon and evening winds of 20 to 30 mph with gusts to 50 mph will surface across the mountain ridges and desert passes through early next week.

 

 

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)

A low pressure system will move into central California today and across the southcentral Nevada on Thursday bringing an increase in winds to much of the area and unsettled weather over the Sierra and central Nevada.

 

 

SPECIAL NOTES:

2018 Fire Season Outlook

 

Recent rains have helped produce a grass crop adequate enough to carry fire into all fuel types this year.

  • Heavy fuel loading exists over Northern California, and to a large degree, over Central California.
  • Fire activity (grass) should begin by the start of May over Southern California, late May over Central California, and by early to mid-June over Northern California.
  • Fire activity will transition into the heavier fuel types much earlier this year compared to last year over the southern portions of the state.
  • There will be the potential for earlier than normal team deployments over Southern California.
  • The Monsoon will govern fire activity over much of Northern California, away from the coast.
  • Large fire potential will be greatest across the Sierra Foothills this summer due to significant tree mortality.

 

DAILY FUELS/FIRE POTENTIAL:

The potential for large fire will continue to be low through early next week due to cool and humid conditions away from the deserts. Light initial attack activity will be possible during the afternoon hours through early next week.

 

SANTA ANA WILDFIRE THREAT INDEX: TODAY: GREY-NO RATING

Twelve large fires have burned more than 200,000 acres in six states. Two new large fires were reported in Arizona. Firefighters were able to contain four large fires in Texas, including the McDannald Fire.

You might think that building a home in the wildlands means you don’t need to landscape. But keeping your home safe from wildland fire means paying special attention to landscaping. Use your imagination: the primary goal is to reduce flammable vegetation for at least thirty feet around your home. Carefully space trees and low growing plants, plant fire resistant shrubbery and flowers. Create walkways and separate your barbecue area. Firewise landscaping adds beauty and safety to your wildland home.
